last time i'll try the equator is 43 kilometres wide the southern tip of the Saraha desert is 1000 kilometres (600 miles) north of the equator...so clearly there are NO deserts on the equator how wide is the equator - Search (bing.com) Earth's diameter at the Equator is about 12,756 kilometers (7,926 miles). At the poles, the diameter is about 12,714 kilometers (7,900 miles). Earth's equatorial bulge is about 43 kilometers (27 miles)
